Are Contemporary Windows Energy Efficient?

8/10/2015 4:50:27 PM

Since glass is a poor insulator, many people are concerned about the energy efficiency of contemporary windows, which often have larger panes than older windows. Fortunately, thanks to advancements in window technology, contemporary windows are some of the most efficient options on the market.

Advanced Window Technology

Today’s most efficient windows share the same types of features. The best frame systems and glazing technologies found in contemporary windows include:
  • Quality frame materials: You have a variety of durable, efficient window materials to choose from. Aluminum-clad, vinyl-clad, fiberglass, fiberglass-clad and wood are all materials that reduce heat transfer and improve insulation.
  • Low-e glass: Special window coatings call low-emissivity, or low-e, allow the glass to reflect infrared and ultraviolet (UV) light. This helps control solar heat gain and loss throughout the year. Low-e coatings are most effective on south- and west-facing windows exposed to direct sunlight.
  • Multiple panes: Two or even three panes of glass with a pocket of air between them insulate much better than a single pane of glass. As an added bonus, having multiple panes increases impact resistance and soundproofing.
  • Gas fills: Some energy efficient windows take the concept of multiple panes one step further by filling the gap with argon, krypton or other insulating gasses. These non-toxic gasses are invisible, but they insulate much better than regular air.
  • Warm edge spacers: These serve two purposes. First, they keep the windows panes at a proper distance apart. Second, they insulate the edge of the window, reducing air leaks.

Benefits of Energy Efficient Windows

When it comes time to upgrade your windows, why is energy efficiency such a concern? By making it a priority, you benefit in the following ways:
  • Lower energy costs: Anything you can do to make your home more efficient lowers your utility bills as a result. Efficient windows accomplish this by reducing air leaks around the frame with tighter seals, lowering heat transfer through the glass with multiple panes, and minimizing the effects of solar heat gain with low-e glass.
  • More comfortable interior: Leaky windows in one room make it feel colder than the rest of the house in winter. Sun pouring in south-facing windows may heat this side of the house to unbearable temperatures in summer. Advanced window technology helps reduce these occurrences for a more even, comfortable temperature throughout your home.
  • Protected furnishings: UV light doesn’t just give you a sunburn; it also fades the color from carpet, wallpaper and furniture. Low-e glass prevents this so your furnishings last longer.
  • Cleaner indoor air: Perhaps you’re replacing old windows that either were designed not to open or lost the ability to operate due to warping and settling. Either way, choosing contemporary windows to circulate outdoor air can improve indoor air quality.
